Answer 1

As you can see from the ENS documentation , web3.js can't performed "reversed resolution", ie getting a ENS name from an address. However, you can do this from the ensjs API like this:

const address = '0xc74E8eFaFE54481bD109f97422AeBca607499f57';
var name = await ens.getName(address)
// Check to be sure the reverse record is correct.
if(address != await ens.name(name).getAddress()) {
  name = null;
}
